Astro 5: output: 'hybrid' no longer exists — 'static' now allows per-page prerender = false
// astro.config.mjs
import { defineConfig } from 'astro/config'
import node from '@astrojs/node'
export default defineConfig({
// output: 'hybrid', // remove: 'static' is the default and behaves like hybrid
adapter: node({ mode: 'standalone' }),
})
---
// src/pages/dashboard.astro (in an endpoint .ts file, the same export goes at the top level)
export const prerender = false
---
An adapter is still required as soon as any route is rendered on demand. Without one you get a warning in dev and an error at build time.
Symptom
An astro.config.mjs with output: 'hybrid' is rejected by config validation on Astro 5+. Agents add output: 'hybrid', or switch the whole site to output: 'server', just to server-render one route.
Cause
Astro 5.0 (2024-12-03, PR #11824) merged hybrid into static. The only values are now 'static' (default: prerender everything unless a route opts out) and 'server' (render on demand by default). Under 'static', any route can opt out with export const prerender = false. Astro 5 also removed dynamic prerender values: only the literals true and false work.
Verify
npx astro build prints the on-demand route as server-rendered and prerenders the rest.
